Schematic for the HP Compaq 8000 Elite business desktop, supplied as a large 13.1 MB PDF. The name gives no board number, form factor or revision, so verify the mainboard part marking before relying on the drawings, since this series shipped in different chassis types. A desktop schematic like this helps trace the ATX standby and main supplies, the CPU VRM, memory voltages and the power button and power-good chain. It also helps locate components on a shorted rail. Its size suggests detailed or scanned pages, so zooming may be needed.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @afsschematicfree. Enginerys does not host this file.
